For a director, the most challenging scenes are the dialogue scenes.

Perhaps the most difficult thing is shooting scenes set 6,000 feet up in the mountains of Mexico.

There were movies that always made me want to be a director. You see brilliant scenes and the way the emotions were handled. I thought, I'd really like to do that.

Film is shot in fragments, and the same moments can be shot again and again until the director is satisfied.

On stage, the audience watches from a fixed viewpoint and the director cannot retake something he doesn't like. It has to work straight through.

The music of the most popular operas is so highly esteemed, it can stand endless revivals.
